What’s covered under your GMC factory warranty, and what’s the best way to protect your investment after it expires?


Whether you are looking for a new GMC, thinking of purchasing one used, or currently own a GMC, protecting your investment should be top of mind. 

New GMC vehicles come with an industry-standard, no-deductible, bumper-to-bumper warranty that’s in effect for a period of 36 months/36,000 miles, whichever comes first. In addition, General Motors Company offers a limited 5-year or 60,000-mile powertrain warranty, as well as additional limited warranties and services detailed below.

While this industry-standard warranty is comprehensive, it’s important to understand its limitations and other long-term ownership considerations, so that you can protect yourself from unforeseen costs after the original factory warranty expires.

Read on for a full breakdown of the GMC warranty and our recommendation for extended warranties. We’ll also fully explain the differences between GMC extended warranties offered at dealerships and those that can be purchased from reputable third parties. 

GMC Warranty Coverage 

The General Motors Company offers new car owners a fairly comprehensive factory warranty that provides financial security against unexpected repairs but only for the first few years of ownership. 

New Vehicle Limited Warranty

GMC provides “bumper-to-bumper” comprehensive coverage for 3 years or 36,000 miles, whichever comes first. This means almost all of the vehicle is protected, with just a short list of exclusions.

Powertrain Limited Warranty

This warranty covers powertrain components like the engine, transmission, and driveline for 5 years or 60,000 miles.

Corrosion Protection

GMC offers protection from elemental rust formation on sheet metal for a period of 3 years or 36,000 miles. This protection is designed to protect against rust from the outside moving inside.

Rust-Through Protection

GMC offers protection from rust and corrosion on sheet metal that spread inside to outside for 6 years or 100,000 miles. This coverage does not include rust from road salts, etc. 

Roadside Assistance

24/7 roadside assistance is available throughout the 5-year/60,000-mile warranty period. 

Courtesy Transportation

Whenever warranty repairs are needed, several transportation options and/or reimbursement of certain transportation expenses are available for your convenience. 


What Isn’t Covered Under Your GMC Factory Warranty?

Although the GMC factory warranty is comprehensive for a short period of time, it’s important to know not everything is covered. Typically, a warranty is in place to cover defects in quality, assembly, or workmanship and not things beyond the control of GMC, such as:

  • Regular maintenance (oil, tire rotation, etc. ) 
  • Tire defects (Tire manufacturers have their own warranty.) 
  • Damage caused by neglect
  • Accidents 
  • Normal wear and tear items (brakes, tires, etc.)

Modern Car Systems Require Long-Term Protection

Modern vehicles are incredible machines that contain dozens and dozens of computer-controlled systems that are instrumental to the daily operation of a vehicle. Vehicles now stop themselves to avoid accidents, call for help when needed, and even allow users the ability to browse the internet while inside. 

Beyond that, a vehicle’s central control system operates your vehicle’s entertainment systems, HVAC, and even (if so equipped) your vehicle's heated or cooled seats. These systems are incredibly complex and incredibly expensive – leading to potentially hefty repair bills down the line if you don’t have proper coverage.

The respected publication Consumer Reports includes a section for “In-Vehicle Electronics” in its reliability studies and notes the continued staggering rise in complaints from consumers. 

Why does this all matter? Well, when looking at the long-term investment you make when purchasing a vehicle, it’s important to consider all possible scenarios in order to protect your investment. A GMC extended warranty will provide extra peace of mind after your factory warranties expire and can cover all vehicle components and systems – not just the systems that move the car down the road. 

According to J.D. Power, General Motors Company ranks in the 22nd out of 32 in initial quality, placing it in the lower third of vehicle reliability amongst other manufacturers. Traditionally GMC has been known for its reliability and durability. However, in recent years, it has begun to slip in reliability ratings, especially amongst its popular SUV offerings. 

Why Do We Recommend Getting An Extended Warranty?

An extended warranty for your GMC truck or SUV comes with something almost invaluable: peace of mind. It’s your protection against having to budget for additional repairs on your daily driver after the warranty expires. In many cases, one or two repairs covered by an extended warranty can pay for the entire cost of the warranty. 

According to RepairPal, here are some common repairs on GMC Vehicles: 

  • Replace a transmission on a 2015 GMC Acadia is $4,503 to $4,589.
  • Replace a water pump on a 2014 GMC Sierra is $556 to $621.
  • Repair a head gasket on 2015 GMC Yukon is $968 to $2,659.

Remember those in-vehicle electronics mentioned earlier? Here the prices can become even more staggering. Take a look at 2015 GMC Yukon Infotainment System – the part alone is $1,395, and remember, it does not include installation, which will run an additional $250–$350. 

Finding The Best Extended Warranty Provider 

Whether you are ready to purchase a new or used GMC or already own a GMC, you have the option to purchase an extended warranty directly through a dealer or through reputable third parties. Word to the wise: caution must be taken, as not all warranties are created equal.

GMC offers extended protection through either its Extended Limited Warranty or the GMC Platinum Protection Plan. The Extended Limited Warranty is only available on new GMC vehicles, while the Platinum Protection Plan is available on new, used, and GMC vehicles.

GMC Extended Limited Warranty

GMC offers consumers the option of extending their “bumper-to-bumper” factory warranty during the new car purchase process through an Extended Limited Warranty. 

Details include: 

  • Offered on newly purchased GMC vehicles
  • Extension bumper-to-bumper coverage
  • Pushes coverage to 5 years/60,000 miles
  • Not available in California, Florida, Maine, or Minnesota
  • Pricing available only through dealer contact 
  • Transferable

GMC Platinum Protection

GMC offers its customers a vehicle service contract administered by third-party company AMT Warranty Corp. This extended warranty can be purchased from a GMC dealer and broken up into monthly payments or paid for up front. 

Details include:

  • Offered on new, used, and currently owned GMC Vehicles 
  • The maximum length of term is 5 years/60,000 miles
  • Not quite bumper-to-bumper coverage
  • Deductible required to receive the repair services
  • Transferable
  • Silver-level coverage available (stated component coverage)

A key thing to keep in mind when looking at purchasing a GMC extended warranty through a dealership is how you will pay for it. Oftentimes, dealers will include the cost of such plans into the financing of the vehicle – meaning you’re paying interest. This interest can really add up over the course of the loan. Also, the GMC plans are limited in what they cover or the length of time that they cover your car. 

GMC Platinum Protection Pricing

Pricing for GMC’s Platinum Protection Plan varies based on vehicle type, location, and coverage length.

We pulled a few pricing examples for a 2019 GMC Acadia with all-wheel drive in Nevada: 

  • 24 months/24,000 miles: $1,543
  • 36 months/36,000 miles: $2,451
  • 48 months/48,000 miles: $3,197
  • 60 months/60,000 miles: $3,153

After our analysis of these factory plans, we believe that third-party companies like EnduranceCARCHEX, and CarShield offer owners much more customization and comprehensive coverage choices. These companies offer more customizable plans to fit your budget while offering the protection to help ensure your peace of mind.
